Here is our experience with travelup We booked RoyalBrunei return flights from London to vietnam from 20/10 to 4/11/2018 through travelup. Everything seems smoothly from the beginning until the return flight. On the way back from vietnam to London with a transit to Brunei airport has been cancelled and rescheduled jntil the next day. However, we have not received any email, notification, sms, or call reminder from the agency or from the airline. Luckily when we did the checkin we found ouf the issues and try to fix the issue with the airline and the agency. However, this is where the nightmare began The emrgency line of travelup customer service was a joke. We couldnt contact them. We had to call at least 5 times for 2 hours to get someone om phone and ask for help. Hoqwver, instead of supporting us or at least checking our flight stagus, this person had NOT even bother to get our information or flight number. He acted unprofessionally and raising his voice and tell us that travelup did not have a y responsibility to help me and my partner. We also tried to contact the normal chstomer service. However, it seems very difficiult to ask them for help. So we gave up with travelup and went directly to the airport and tried to find the support there from the airline. Luckilly, everything has been sorted. However, the experience I had with tis company was so bad, so I recomend to not booking from this company
